fclone | Clone objects by dropping circular references

I am working solo on an employee timekeeping project which uses a database to store time sheet entries. I am using Delphi Pro 10.2.3 Tokyo for the project and have created a library of wrapper classes to facilitate working with datasets like normal classes. For example, to access the FirstName field in the Employee table, I can write LFirstName := FEmployee.FirstName; rather than LFirstName := Dataset.FieldByName('FirstName').AsString;

Some of my classes have a significant number of dependencies (as many as eight) which I am injecting through the class' constructor. I use a domain object to create the required interfaces and inject them into the class being created. Some of the interfaces being injected themselves are also very complex and it is starting to get difficult to keep track of everything in the domain object.

The dependencies being injected include wrapper interfaces for other tables which provide lookup values for calculated fields, pointers to functions which create create objects used by the class or call back functions which resolve master/detail relationships. These relationships are static and need to be set in the constructor so that any calculated fields will function when the class is created.

Are there any alternatives to constructor injection which might may decrease complexity of the constructor while maintaining decoupled classes. Here is a sample of code from one of my modules for time sheet entries.
